Specification of Letters Patent.

Patented Feb. 11, 1919.

Application filed February 27, 1917. Serial No. 151,233.

To all whom it may concem:

Be it known that I, STEFFEN A. BROWN, a citizen of the United States of America, and resident of Yonkers, in the count of Westchester, in the State of New ork,

have invented new and usefulImprovements means for attaching the pump to the tank,

whereby the operating lever or handle may be made to swing horizontally or substan-.

tially so in a plane most convenient to the operator when standing upon the floor or tank support.

In devices of this character, it is frequently necessary to draw the water or other fluid from'a considerable depth or vertical height, while in other instances the source of supply from the tank is at a relatively low level, and it, therefore, follows that the operation of the same pump for drawing water from the greater vertical depth would require a proportionate increase of power applied to the operating lever, and in order that the same device may be operated with substantially the same'degree of power, it is necessary to proportionately,

increase the leverage of the pump-operating handle. i

This necessary variation in the length of thelever'is practically prohibitive in levers which oscillate in a vertical plane, by reason of the fact that the handle mustalways be at approximately the height of the arms of the operator when extended.

The main object, therefore, of my present invention is toenable the lever to be extended to any desired length for obtaining the necessary power without materially varying its height in any position of adjustment. i

Another object is to provide simple means wherebythe pump may be clampedto the tank at a height most convenient V to the operator after it has been piped to the tank and to the source of upply. l

Qther objects and uses relating to specific parts of the apparatus will be brought out in the following description.

In the drawings Figure 1 is a perspective view of a combined tank and double-acting force pump embodying the features of my invention.

Fig. 2 is an enlarged transverse sectional view of the same apparatus taken in a plane between the point of attachment of the operating lever and head of the pump cylinder, and showing particularly the manner of attaching the pump to the tank.

In order that my invention may be clearly understood, I have shown a horizontally disposed tank A of any desiredcapacity having the usual water gage ar and pressure indicator a connected thereto.

Any well-known commercial type of double-acting piston pump B may be employed for filling the tank under pressure, said pump being disposed horizontally and provided with the usual intake pipe -Z) leading to the source of supply, as a well,

spring'or cistern, not shown, and a delivery pipe b leading to the interior of the tank.

The head of the pump cylinder is provided with a horizontally disposed frame 1- projecting therefrom for guiding the stem, as 2, of the pump piston and also for receiving and supporting a hand lever 3 which is pivoted at '4 to the frame -1-, to swing in a horizontal plane at a height most convenient for the operator and usually at approximately the height of the arms when extended forwardly.

The lever-3is preferably of the first kind and may be connected to the piston stem 2 by any suitable mechanism for transmitting motion thereto, but preferably by a toothed segment 5 on the inner end thereof, meshing with a toothed rack 6- on the stem 2, the latter being held in mesh with the segment 5' by means of a pin or roller bearing 7- bearing against the rear face. thereof in a manner wellknownto those skilled in this art, and not necessary to herein-illustrate in detail.

The distance between the fulcrum 4- and pitch line of thegearteeth 5-- and .6- is relatively short, while the distance between the fulcrum and free end of the handle -3 may be of any suitable length according to the power required to operate the pump for drawing water from any practicable depth and forcing the same into the tank -A.

By using the horizontally swinging lever, it is only necessary to set the pump at such approximate height as will bring the lever in a horizontal plane nearly the same height from the floor as that of the operators arms when extended forwardly in the attitude of operating said handle, thereby avoiding the necessity for extremely careful measurements of the piping in connecting the pump to the tank.

This piping, as b and b-, serves to partially support the pump at the desired elevation, but is not sufiicient for retaining the pump rigidly without liability of straining the pipe connections, both with the tank and pump, and I have, therefore, provided an additional pump support in the form of circular bands or split rings -8 passing circum'ferential'ly and adj ustably around the tank and secured at one side to a lug or bracket 9 on the adjacent side of the pump B', as shown more clearly in Fig. 2, the opposite ends of the bands at the transverse division thereof being turned outwa'rdly to form lugs 1 0 which are apertured for receiving clamping bolts 11-, the latter serving to draw thebands tightly upon the periphery of the tank, and thereby holding the pump in its adjusted position relatively to said tank.

It is now clear that all portions of the handle are dispo'sedin the same horizontal plane and are adapted to be engaged by the operator for operating the pump without changing the position of the arms vertically,

' thus permitting wide variations in the degree of power in operating the pump by simply changing the positions of the hands nearer to or farther from the fulcrum at the same vertical height;that is, if the water level of the source of supply is only a rela tively short distance below the level of the tank, the handle may be engaged by the operator at a relatively short distance from the fulcrum where the arc of movement is correspondingly small, but if the source of supply isat considerably greater depth, requiring greater power to elevate the same to the tanl'nthe operator simply shifts the position of the hands farther from the fulcrum until the operation of forcing the water from said source of supply into the tankis comparatively easy, although the are of movement of the engaged portion of the handleflwill be somewhat longer in order to accomplish the same length of Stroke of the piston.

The princ'i'pa'l advantage in the use of the horizontal lever, therefore, consists in the ability or as eperaar to ras the handle" at widely varying distances from the fulcrum where the power for operating the pump may be most suitable to the strength of the operator or height from which the water is drawn from the source of supply, it being understood that in the use of a hand lever operating in a vertical plane, this application of a wide variation of power to the lever would be practically impossible without considerable inconvenience and fatiguing labor in bending or reaching to vari ous impracticable heights.

The ends of the bands adjacent the pump are preferably hook-shaped at -12 and assed through suitable apertures in the racket 9 for interlocking connection therewith, thus permitting the clamping members 8 to be easily and quickly at tach'ed to or detached from the pump and periphery of the tank, and at the same time afiording a positive securing and supporting means for the pump. As previously intimated the bands 8-- with the pump thereon may be adjusted circumferentially of the tank --A to bring it to the" desired level or to conform to variations in the lengths of the pipe attached thereto and, together with the specified means for attach' ing the bands to the pump and to the tank, enables the entire pumping outfit to be easily and quickly applied to and removed from similar tanks without tapping or otherwise weakening the same for that purpose.

The reservoir A is also used as a pressure tank for storing the" water under pressure, and for this purpose the pipe I) is provided with a check valve to prevent backflow from the tank to the pump.

What I claim is: f

1. The combination with a tank, of a pump-support clamped adjustably around and upon the periphery of the tank, and a piston pump mounted horizontally upon said support and adjustable therewith relatively to the tank, said pump having operating lever movable in a horizontal plane parallel with the axis of its piston.

2. The combination with a horizontally disposed cylindrical tank, of a pump-support clamped adjustably around and upon 115 the periphery of the tank and provided at one side with hooked-shaped members tending to draw apart when the support is tightened upon the tank and a horizontally disposed pump engaged by said members for 120 adjustment with the support relatively to the tank.
